lithium is a metal element. atomic number of it is 3.
LITHIUM!!
1. The number of a chemical element in the Periodic Table. 2. The number of protons of this chemical element. 3. The number of electrons (in neutral state) of this element. 4. Also the atomic number is proportional to the atomic weight.
Uranium is a natural chemical element, metal, solid, radioactive.The atomic number is 92 and the atomic weight is 238,02891(3).
If that's the bottom left no., it's lithium.
- the atomic number of a chemical element or- the number of a type of an atom in a molecule or- indices for physical/chemical parameters
The number of protons in an atom is the atomic number. It tells you which element the atom is.
This is a consequence of the law of periodicity of chemical elements.
It is the number of protons in the nucleus of the atom and it determinnes many properties of the atom. The atomic number is also the number of electrons and is a constant for every element
The name of the element that has atomic number 3 is Lithium (Li).
The element with the lowest atomic number in period 3 is sodium (Na) with an atomic number of 11.
Magnesium
The solid element with the lowest atomic number is lithium, with an atomic number of 3.
